Description

Technical Field

[0001] This utility model relates to the field of conductive connection technology specifically applicable to high frequency, and particularly to male terminal plug-in modules and male terminal connectors. Background Technology

[0002] As communication equipment develops towards miniaturization, high density, and high speed, the application of high-speed cable connectors is becoming increasingly widespread. Figure 1 The diagram illustrates the structural design of an existing high-speed cable connection assembly by the applicant, specifically a schematic diagram of the mating state of a male cable connector composed of multiple male plug-in modules 1 and a female cable connector 2. Figure 2-6 The structure of each part of the male connector module 1 in the high-speed cable connection assembly is shown. From Figure 2-6 As can be seen from the above, the existing male connector module 1 mainly includes a high-speed cable section 10, a terminal module 13, an insulating sleeve 14, and a shielding sleeve. Terminal module 13 includes an insulating component 130 and a male contact injection-molded within the insulating component 130. Both ends of the male contact extend from both ends of the insulating component 130. The rear end of the male contact extending from the insulating component 130 is a wiring terminal. The male contact extends a length from the front end of the insulating component 130, forming a cantilever section 131. The front end of the cantilever section 131 has a contact portion for conductive contact with an adapter contact. The wire core of the height cable portion 10 is connected to the wiring terminal on the terminal module 13. The insulating sleeve 14 includes a hollow cuboid body. One end of the body is for the adapter female contact to extend into the insertion port. The other end has two snap-fit ​​arms extending from its width direction to snap into the width directions of the insulating component 130. After the insulating sleeve 14 snaps into the front of the insulating component 130, the contact extends into the insulating sleeve 14. A shielding cylinder completely encloses the terminal module and the insulating sleeve, providing shielding for the insertion position.

[0003] Combination Figure 2-7It can be seen that the shielding cylinder of the existing male plug-in module has a split structure, including a U-shaped bottom shell part 12 and a flat cover plate part 11 that is fixedly fastened to the opening of the bottom shell. The two parts are fastened together to enclose the terminal module 13 and the insulating sleeve 14. The insulating component of the terminal module 13 is snapped into the two snap-fit ​​arms of the insulating sleeve 14. The insulating sleeve 14 has limiting protrusions 140 on both sides in the thickness direction. The shielding cylinder has limiting protrusions 124 for corresponding concave-convex engagement with the side of the insulating component 130 and limiting holes 110 for engaging with the limiting protrusions 140 on both sides in the thickness direction. Moreover, the insulating sleeve 14 and the shielding cylinder have corresponding sleeve clearance holes 141 and shielding cylinder clearance holes 111 on both sides in the thickness direction to avoid elastic deformation of the male contact in the plugged-in state. When the male connector module 1 is inserted into the female cable connector 2, the female contact of the female cable connector 2 extends from the insertion port into the insulating sleeve 14 and connects with the male contact of the male connector module 1. This existing male connector module has a high degree of integration, a small size, and achieves full shielding of the insertion position through the shielding sleeve, avoiding crosstalk between different signals.

[0004] However, in the aforementioned prior art, the insulating sleeve extends forward from the terminal module to the front end of the shielding cylinder, completely enclosing the portion of the male contact protruding from the front of the terminal module and the insertion point of the male and female contacts. While this structure ensures reliable insulation between the male contact and the shielding cylinder, the ideal high-speed signal transmission model involves setting a fully shielded structure surrounding the transmission line at a suitable (not too large, preferably small) distance outside the signal transmission line, with air insulation is used to isolate the signal transmission line from the fully shielded structure. The aforementioned existing design is not conducive to high-speed signal transmission. Utility Model Content

[0005] The purpose of this invention is to provide a male-terminal plug-in module to solve the problem that, although existing male-terminal plug-in modules have relatively reliable insulation between the male contact and the shielding cylinder, they are not conducive to high-speed signal transmission. Simultaneously, this invention also provides a male-terminal connector to solve the problem of poor high-speed signal transmission performance in existing male-terminal connectors.

[0006] The male terminal plug-in module of this utility model includes a shielding cylinder and a terminal module fixedly installed inside the shielding cylinder. The terminal module includes an insulating component and a male terminal contact fixed inside the insulating component. The male terminal contact has an overhanging section extending forward from the front end of the insulating component. The front end of the overhanging section has a contact portion for engaging and communicating with a mating contact. The front part of the shielding cylinder at the front end of the insulating component is an air cavity that only accommodates the overhanging section.

[0007] Furthermore, the cantilever sections are arranged in pairs, and an insertion space is formed between the two cantilever sections of the same pair for inserting the adapter contact. The shielding cylinder has a near-ground protrusion on each of the two opposite sides of the cylinder wall in the parallel direction of the two cantilever sections of the pair, which is located at the front side of the front end of the cantilever section.

[0008] Furthermore, the shielding cylinder is a cylindrical structure with a rectangular cross-section, and each pair of cantilever sections are arranged at intervals in the width direction of the shielding cylinder. The near-ground protrusion is rectangular and its width is such that its projection in the thickness direction can cover all the adapter contacts.

[0009] Furthermore, the front end of the cantilever section is provided with an insertion guide section that bends toward the shielding cylinder. The insertion guide sections of the paired cantilever sections extend in opposite directions to form a flared structure for guiding the adapter contact into the insertion space. The shielding cylinder is provided with a clearance hole on the cylinder wall corresponding to the insertion guide section and at the position corresponding to the end of the insertion guide section.

[0010] Furthermore, the near-ground protrusion is located adjacent to the clearance hole and in front of the clearance hole.

[0011] This invention is an element-omitting invention. By eliminating the insulating sleeve inside the shielding cylinder that wraps the overhanging section of the male terminal contact in the prior art, it not only simplifies the structure of the male terminal plug-in module, but also improves the high-speed transmission performance of the male terminal plug-in module by isolating the overhanging section from the shielding cylinder through air insulation.

[0012] The male connector of this utility model includes a male insertion module, which includes a shielding cylinder and a terminal module fixedly installed inside the shielding cylinder. The terminal module includes an insulating component and a male contact fixed inside the insulating component. The male contact has an overhanging section extending forward from the front end of the insulating component. The front end of the overhanging section has a contact portion for engaging and communicating with a mating contact. The front part of the shielding cylinder at the front end of the insulating component is an air cavity that only accommodates the overhanging section.

[0013] Furthermore, the cantilever sections are arranged in pairs, and an insertion space is formed between the two cantilever sections of the same pair for inserting the adapter contact. The shielding cylinder has a near-ground protrusion on each of the two opposite sides of the cylinder wall in the parallel direction of the two cantilever sections of the pair, which is located at the front side of the front end of the cantilever section.

[0014] Furthermore, the shielding cylinder is a cylindrical structure with a rectangular cross-section, and each pair of cantilever sections are arranged at intervals in the width direction of the shielding cylinder. The near-ground protrusion is rectangular and its width is such that its projection in the thickness direction can cover all the adapter contacts.

[0015] Furthermore, the front end of the cantilever section is provided with an insertion guide section that bends toward the shielding cylinder. The insertion guide sections of the paired cantilever sections extend in opposite directions to form a flared structure for guiding the adapter contact into the insertion space. The shielding cylinder is provided with a clearance hole on the cylinder wall corresponding to the insertion guide section and at the position corresponding to the end of the insertion guide section.

[0016] Furthermore, the near-ground protrusion is located adjacent to the clearance hole and in front of the clearance hole.

[0017] The male connector of this invention eliminates the need for the insulating sleeve that wraps the cantilever section of the male contact inside the shielding cylinder of the existing male connector module. This not only simplifies the structure of the male connector module but also improves the high-speed transmission performance of the male connector module by providing air insulation between the cantilever section and the shielding cylinder, thereby enhancing the overall signal transmission performance of the male connector.

[0030] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0031] This invention, based on an ideal model of high-speed signal transmission, departs from the conventional design of placing an insulating medium between the signal transmission line and the fully shielded structure surrounding it. It optimizes the existing male connector module by omitting the insulating sleeve, simplifying its structure and improving the high-speed transmission performance by providing air insulation between the overhang and the shielding cylinder. This enhances the overall signal transmission performance of the male connector. Furthermore, research has shown that in practical engineering, when the adapter contact and the male contact are engaged and conducting, the floating displacement of the male contact perpendicular to the insertion direction does not significantly affect the insulation performance. Therefore, omitting the insulating sleeve does not actually reduce insulation performance.

[0032] Based on the above concept, the following provides various embodiments of male connector modules for illustration.

[0033] The male connector includes a male connection module, which is a high-speed connection module. It includes a shielding cylinder and a terminal module 13 fixedly installed inside the shielding cylinder. The terminal module 13 includes an insulating component 130 and a male contact fixed inside the insulating component 130. The male contact has an overhanging section 131 extending forward from the front end of the insulating component 130. The front end of the overhanging section 131 has a contact portion for mating and conducting with the adapter contact. The structure of the terminal module 13 and the male contact is the same as that of the terminal module 13 and the male contact in the prior art, and will not be described in detail here. This article focuses on the fact that, compared to the existing technology where the shielding cylinder has an insulating sleeve 14 installed on the front side of the insulating component 130 of the terminal module 13, the shielding cylinder of this utility model has an air cavity that only accommodates the cantilever section 131 in the front part of the insulating component 130. That is, the insulating sleeve 14 is omitted, thereby achieving the purpose of air insulation isolation between the cantilever section 131 and the shielding cylinder, improving the high-speed transmission performance of the male terminal plug-in module 1.

[0034] Based on this basic embodiment, in a more preferred embodiment, the cantilever sections 131 are arranged in pairs, and an insertion space is formed between the two cantilever sections 131 of the same pair for inserting a mating contact element. Figure 3-4 As can be clearly seen in sections 8-10, the shielding cylinder has a rectangular cross-section. Two pairs of cantilever sections 131 are arranged at intervals along the width of the shielding cylinder. The main difference between the shielding cylinder and existing shielding cylinders is that the shielding cylinder has near-ground protrusions 15 on opposite sides of the cylinder wall in the parallel direction (i.e., the thickness direction) of the two pairs of cantilever sections 131. These near-ground protrusions 15 are located at the front side of the front end of the cantilever section 131. When the male end contact and the adapter contact are inserted, the sheet-like adapter is inserted into the insertion space formed between the two pairs of cantilever sections 131. After the adapter contact is inserted into the insertion space, the two pairs of cantilever sections 131 are pushed to opposite sides by the adapter contact to keep them pressed against each other. Therefore, the distance from the cantilever section 131 to the cylinder wall on the same side of the shielding cylinder is less than the distance from the adapter contact to that cylinder wall. Figure 11 As shown, in this embodiment, due to the provision of the near-ground protrusion 15, after the male end contact and the adapter contact are inserted, the difference between the distance L from the cantilever section 131 to the wall of the shielding cylinder on the same side and the distance l from the adapter contact to the wall of the cylinder is reduced and made closer. This makes the distance between the grounding shield on the outside and the signal transmission path more uniform on the extension path of the signal transmission line, which is beneficial to ensuring the signal transmission quality.

[0035] Of course, in the above embodiments, the parallel direction of the paired overhanging sections 131 is in the thickness direction of the shielding cylinder, so the near-ground protrusion 15 is provided on the two opposite cylinder walls in the thickness direction of the shielding cylinder; in other embodiments, if the parallel direction of the paired overhanging sections 131 is in the width direction of the shielding cylinder, then the near-ground protrusion 15 can be provided on the two opposite cylinder walls in the width direction of the shielding cylinder.

[0036] Based on the aforementioned purpose of the near-ground protrusion 15, in a preferred embodiment, the near-ground protrusion 15 is rectangular, and its width is such that its projection in the thickness direction can cover all the adapter contacts. Furthermore, the dimensions of the near-ground protrusion 15 in the front-back direction can cover as many adapter contacts as possible. In actual processing, it can be directly stamped onto the corresponding cylinder wall of the shielding cylinder.

[0037] In one embodiment, similar to existing male contact structures, such as... Figure 4 , 8 As shown in Figure 11, the front end of the cantilever section 131 is provided with an insertion guide section that bends towards the shielding cylinder. The insertion guide sections of the paired cantilever sections 131 extend in opposite directions, forming a flared structure for guiding the adapter contact into the insertion space. The shielding cylinder has a clearance hole on the cylinder wall corresponding to the insertion guide section, at the position corresponding to the end of the insertion guide section. This can minimize the possibility that the protruding part at the end of the insertion guide section is too close to the shielding cylinder, i.e., the ground potential, after the adapter contact is inserted into the insertion space. In a more preferred embodiment, the near-ground protrusion 15 is disposed adjacent to the clearance hole and located in front of the clearance hole, so that the size of the near-ground protrusion 15 in the front-back direction can cover the adapter contact as much as possible.

[0038] In the above embodiment, the near-ground protrusion 15 is an integral protrusion that corresponds to two adapter contacts. In other embodiments, two near-ground protrusions 15 can be provided, and the two near-ground protrusions 15 correspond to two adapter contacts respectively. That is, the number of near-ground protrusions 15 corresponds one-to-one with the number of adapter contacts.

[0039] An embodiment of the male connector of this utility model: The male connector includes multiple male plug-in modules 1 and a housing that fixes the multiple male plug-in modules 1 together. The specific structure of the male plug-in module 1 is the same as the structure of the male plug-in module 1 described above, and will not be repeated here.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
